abot89-11 abot89-11 This rare member of the ginger family (Zingiberaceae) is restricted to monsoonal forest margins and grasslands in central Myanmar. The conspicuous floral parts are highly modified sterile stamens, or staminodia. Results of phylogenetic analyses based on molecular data have provided new information on relationships among the 50+ genera of the family and form the basis for a new classification as well as setting the stage for investigations of the biogeographic history and floral character evolution in this tropical group of monocots. copyright: BSA,

abot89-5 abot89-5 A silique of Arabidopsis thaliana enclosing ovules containing torpedo-shaped embryos cultured horizontally in a hormone-free, sucrose-containing medium, photographed 25 d after culture in the dark and 1 d in continuous light. Seedlings arise by viviparous germination of embryos, which complete their development but do not lapse into dormancy. Normal plants are raised by subsequent transplantation of seedlings to soil vermiculite. copyright: BSA,

abot89-8 abot89-8 The bull banksia (Banksia grandis) of southwestern Australia. New molecular data suggest that a clade of erect and prostrate shrub banksias with tough, serrate leaves is more closely related to the co-occurring genus Dryandra than to this and other species of tree banksias. copyright: BSA,

abot89-9 abot89-9 A syrphid fly (Toxomerus spp.) visits a wild radish (Raphanus raphanistrum) flower. Syrphids are one of a variety of effective pollinators of wild radish, which also include bumble bees, honey bees, sweat bees, and cabbage butterflies. The strength of selection exerted by these pollinators and the heritability of floral traits in the field are lessened by a large degree of within-plant variation in these traits. copyright: BSA,

abot90-1 abot90-1 A snap trap of the Venus's flytrap, <IT>Dionaea muscipula</IT> Ellis ex L. (Droseraceae), native in North America forms a sister group with widely distributed aquatic snap trap species Aldrovanda vesiculosa L. copyright: BSA,

abot90-10 abot90-10 The three most abundant Venezuelan columnar cacti, from left to right, Pilosocereus lanuginosus (Linnaeus) Byles & Rowley, Stenocereus griseus (Haworth) Buxbaum, and Cereus repandus (Linnaeus) Miller. These species depend strictly on nectar-feeding bats for their pollination. Bat-mediated gene dispersal confers high levels of genetic exchange among populations of the three species, a process that enhances levels of genetic diversity within their populations. copyright: BSA,

abot90-11 abot90-11 The golden heads of Balsamorhiza and Wyethia covering the foothills herald spring in Utah's Wasatch Mountains. Balsamorhiza macrophylla, the cutleat balsamroot (shown here), commonly grows interspersed with B. sagittata (arrowleaf balsamroot) and W. amplexicaulis (mule's ear) on hillsides and in open woods. copyright: BSA,

abot90-12 abot90-12 A phylogeny of angiosperms based on matK, a plastid gene nested within the trnK intron. Illustrations are superimposed on photographs of representative taxa from major angiosperm lineages, with Amborella shown in the center. We thank Peter K. Endress for providing photographs of Chloranthus and Ceratophyllum, Porter P. Lowry II for Amborella, and Duncan M. Porter for Tiarella (Saxifragaceae). copyright: BSA,

abot90-2 abot90-2 <IT>Monophyllaea horsfieldii</IT> R.Br., cultivated at the Botanical Garden Vienna (HBV), grown from seeds collected by Dr. Kwiton Jong at Batu Caves, Selangor, West Malaysia. The plant represents a giant seedling, with the stem corresponding to the hypocotyl and the single leaf to an enormously enlarged cotyledon. As flowers and fruits are produced in the seedling stage, <IT>Monophyllaea</IT> provides a perfect example of neoteny in the plant kingdom. The genus belongs to the morphologically and biogeographically noteworthy tribe Epithemateae of Gesneriaceae. copyright: BSA,

abot90-3 abot90-3 <IT>Artibeus lituratus,</IT> the great fruit bat, feeding on the infructescences of <IT>Cecropia</IT> sp. Species of <IT>Artibeus</IT> are important dispersers of <IT>Cecropia.</IT> Morphological and anatomical study has revealed that the dispersal unit of <IT>Cecropia</IT> is the entire fruit, not just the seed. Bats consume the fleshy floral parts surrounding the fruits and disperse the fruits. copyright: BSA,

abot90-4 abot90-4 Asplenium aureum Cav. photographed in a remnant of laurel forest in the Barranco del Laurel, Gran Canaria. This species is endemic to the Canary Islands and is the largest within subgenus Ceterach.Molecular data suggest the polyphyly of subgenus Ceterach(Willd.) Bir et al., implicating homoplasy in the lamina shape and the dense scale cover, characters previously used to circumscribe this group. copyright: BSA,

abot90-5 abot90-5 Pollen germination and tube growth in the snow buttercup, <IT>Ranunculus adoneus,</IT> photographed under fluorescence microscopy. Snow buttercup flowers exhibit heliotropism, the capacity to track the sun's rays over the course of the day. The adaptive significance of solar tracking in snow buttercups is mediated through the impact of flower heliotropism on paternal and maternal floral environments. In controlled crosses, pollen from solar-tracking flowers has higher germination success than pollen from experimentally restrained flowers. Solar tracking in recipient flowers also enhances pollen germination and increases pollen tube to ovule ratios. copyright: BSA,

abot90-6 abot90-6 Cross section through the dehisced anther of Xylopia collina of the pawpaw family (Annonaceae). Species of the genus Xylopia, as well as other members of this family, produce large pollen that is shed in units of four or sometimes even 32 grains (some tetrads visible in illustration). Associated with these compound pollen units in most genera are layers of sterile tissue, called septa, that separate the grains into chambers within each anther. Tsou and Johnson investigated the variation and development of the septa of Annonaceae, and found that despite variability in appearance, the septal tissues of all species were formed by the same developmental pathway. They propose that these tissues may have evolved in Annonaceae in response to a requirement for extra nutrients and support tissues for large pollen units. copyright: BSA,
